I take it that has to do with heat transfer?

I don't know if it will make a difference or not. My plan is using a decent blend oil for 5k OCI's which are all highway. Using Top Tier fuel, and a sea-foam treatment once a year. Plus changing the PCV valve every 50k.
Some say "getting on it" once a day will help. Which she does getting on the freeway.
We're going to keep this thing for 200k, so we'll see how it goes. I'll check back in about 5-6 years at the 200k mark. lol.

My brain hurts from reading that patent!!! I could have gone longer in life without knowing what a Mannich Condensate is. Readers, don't read that patent if you want to preserve what neurons you have left. Have a beer and watch some football instead.
Seriously, I wonder if GF-6 or dexos2016 will use Lubrizol's high tech chemistry or the equivalent, and test for intake valve deposits (IVD).
That patent indicates which oil you use can have an effect on IVD. Figuring out which oil is best might not be possible.

There are quite a few, 'over 100k miles' 2.4 GDI applications out there already. No widespread IVD issues have been reported.

Nothing to do with GDI intake valve deposits. Thats the Alabama engine plant leaving metal particles inside the engine. "The company said that the 2011 Sonata was the first Hyundai vehicle to use engines made in Alabama, where the company initially used a mechanical process to remove machining debris from the crankshaft. That process was changed to a high pressure wet blasting system in April of 2012."

Seafoam has been tested already. It cannot touch the hard deposits left on intake valves of DI engines. It can only remove soft, gummy buildup. Don't waste the time.

Seafoam=snake oil. Just like MMO.
I think I would use water injection into the intake manifold if I owned one of these GDI smogger engine cars. Maybe use the system to inject some PEA or other substance to keep the valves clean.
I'd try something because I tend to keep a daily driver for a long time. For most people, they should just ignore the problem and trade up before the factory warranty runs out. Keeping a car beyond the warranty can sometimes be an unreasonable risk.

It's done through the intake hose. Some say it is "fake", but if used as a preventative measure once a year instead of waiting until 75-100k when the deposits are caked on there it does a decent job. Do a youtube check where people have done some tests with positive results. Is it the cure all? No, but it is worth a shot until some definitive process comes out, that doesn't involve a top end tear down.

Start with this part:
The amino compound may be characterized by the presence within its structure of at least one HN< group and can be a monoamine or polyamine. Mixtures of two or more amino compounds can be used in the reaction with one or more acylating reagents. In one embodiment, the amino compound contains at least one primary amino group (i.e., —NH2). In one embodiment, the amine is a polyamine, for example, a polyamine containing at least two —NH— groups, either or both of which are primary or secondary amines. The amines may be aliphatic, cycloaliphatic, aromatic or heterocyclic amines. Hydroxy substituted amines, such as alkanol amines (e.g., mono- or diethanol amine), and hydroxy (polyhydrocarbyloxy) anologs of such alkanol amines' may be used.
Among the useful amines are the alkylene polyamines, including the polyalkylene polyamines. The alkylene polyamines include those represented by the formula ...
... U may be ethylene or propylene. Alkylene polyamines where each R is hydrogen or an amino-substituted hydrocarbyl group with the ethylene polyamines and mixtures of ethylene polyamines are useful. Usually n will have an average value of from about 2 to about 10. Such alkylene polyamines include methylene polyamines, ethylene polyamines, propylene polyamines, butylene polyamines, pentylene polyamines, hexylene polyamines, heptylene polyamines, etc. The higher homologs of such amines and related amino alkyl-substituted piperazines are also included.
Alkylene polyamines that are useful include ethylene diamine, diethylene triamine, triethylene tetramine, tetraethylene pentamine, pentaethylene hexamine, propylene diamine, trimethylene diamine, hexamethylene diamine, decamethylene diamine, octamethylene diamine, di(heptamethylene)triamine, tripropylene tetramine, trimethylene diamine, di(trimethylene)triamine, N-(2-aminoethyl)piperazine, 1,4-bis(2-aminoethyl)piperazine, and the like. Higher homologs such as those obtained by condensing two or more of the above-illustrated alkylene amines may be used. Mixtures of two or more of any of the afore-described polyamines may be used.
Useful polyamines include those resulting from stripping polyamine mixtures. In this instance, lower molecular weight polyamines and volatile contaminants are removed from an alkylene polyamine mixture to leave as residue what is often termed “polyamine bottoms”. In general, alkylene polyamine bottoms can be characterized as having less than about 2% by weight, and in one embodiment less than about 1% by weight material boiling below about 200° C.
