Finally got to watch this in my home theater room, here are somethings I noticed:

After being slapped by K2SO, you can see Diego Luna slightly smirking while hiding his face
Vader’s “outfit” on Mustafar looks like a Halloween costume, yet it looks fine in the finale
The color timing is aimed more at theatrical colors for ANH, while TFA is aimed towards the Blu-ray colors
Tarkin is so close to looking real, it almost throws the whole illusion off
Riz Ahmed talks way too fast
The score is one of the best Star Wars soundtracks ever

All in all, it’s such a great film and rivals The Force Awakens in every aspect. I can’t believe I hated it when it first came out.
