It's impossible to know much from one oil change. A poorly tuned Camry 4cyl will show symtoms of poor drivability. I think it wise to make sure your air filter is right and intake hose is good and run a few more intervals to see if you have the similar numbers.
It's difficult to know(unless you have ALL the records)that it has always had 3K intervals at the dealer. Every dealer is different and some will advise 3K intervals and some will advise 7.5K intervals so REGULAR maintenance from a dealer can mean good things or bad things.
Based on my experience with Yodas, the Camry's with the old 2.2 belt driven motor will never be a good candidate for long oil change intervals(over 7.5K WITH a top-notch synthetic). The head design along with the balance-shaft design are hard on oil and only holding 3.8qts. does not help either. The analysis I have done on my mom's Camry(2.2L) shows that it likes a HDEO in the 5W40 weight. These engines do well on a high TBN oil like Amsoil,Schaeffer9000, Rotella T 5W40. Her Camry has not shown any significant MPG loss by running a HDEO 5W40.
I've worked on them a long time. Send me a PM if you ever need any info and i'll be glad to help if I can.
