Sorry to hijack............. Love that Avatar!!!!!!!!!
I believe the answer is they are all "true 30 weights".
There isn't something being labeled XW-30 that isn't actually in accordance with the accepted range. With the exception of non approved oils and those eventually investigated by the PQIA and pulled off shelves.
If you're asking for a 30 weight on the high end of the viscosity, try these:

thickest 30 weight?
after searching i found gc is about 12.2 cst and the cut off for 30 weight is 12.5cst? is there any thicker 30 weight or is gc the thickest?

Thickest 5w30 (11 plus at 100c)
Hello, Trying to find the thickest 5w30 synthetic based on viscosity at 212F. Most Mobil 1 or Pennzoil I was seeing are in the range of 10 to 10.5 Please share your info of any 5w30 I've missed which has kinetic viscosity of 11 plus at 100c Thanks.

You can hardly read a thread here without tripping over some comment about PP, PUP and even PPHM being either "Thin 30s" or "thick 20s" and theories about them being the lines shell passes off it's lighter base stocks on. Even plain Mobil was mentioned to be thin, and you had to go to the HM version to be solidly in the 30 grade. @Hogwash made a comment above right along those lines.
Thanks! When I found it I just had to use it...
I'm talking about the difference between what the bottle says, and what the VOA says.

Maybe some slight variance but still within grade. Each grade has a range.

Viscosities can be related horizontally only Viscosities based on 96 VI single grade oils. ISO are specified at 40°C AGMA are specified at 40°C SAE 75w, 80w, 85, 5w, & 10w specified at low temperature. Equivalent viscosities for 100° & 210°F are shown SAE 90 to 250 and 20 to 50 specified at...

I agree, but I think the contention is that certain 30's are very close to the low end of the range. Too close to stay in grade, unfortunately, based on UOAs available on this forum.Maybe some slight variance but still within grade. Each grade has a range.

The ones of note that I have seen are:
Pennzoil Platinum 5w30
Idemitsu 5w30 (SP/GF6 specifically)
Xw40 is more "guaranteed" to stay or dip to thick 30 weight.

Not slight in some cases.
PUP 5w30 advertises 10.6 cSt at 100c
Many VOAs range it from 9.6 to 9.3 at 100c.
That's not exactly slight variance
Perhaps you should change the title of your thread as all Xw30 oils will fall within the 30 grade range, and is the answer to your original question "which SN+ or SP XW-30s are actual 30 weights currently?"
Whether an oil is on the high/low end of the range, it is still within range. I suggested that you change the title of the thread because now you seem to be straying into a debate about low end range oils staying in grade.

Then it would have to be right in the middle, anything over would be a thickie and anything under would be a thinie.

I think you'll find that the allowed or anticipated variance in measured values for both UOA's and VOA's is higher than you'd like. You don't get XOM lab precision for $20.00.
Now, batch variance is also a thing, so if a particular product concerns you, reaching out to the manufacturer to see what their allowable deviation range for the shipped product may be beneficial.
