There indeed seemed to be quite a bit of variation in many of the canyon scenes; R2 and the Jawas, Luke and 3P0 finding R2 (which is surprisingly colorful in comparison) and the biggest one for me which is Ben revealing himself to Luke. I felt it stuck out when watching v2.0, later realizing it was indeed more accurate to the original source.

Video can do nutty stuff to our memories.

Sorry to chime in late but I've finally gotten down to enjoying 2.5 after my new HDD came in. This is a fantastic upgrade in numerous ways, with nearly everything upgraded, checked off and tweaked to their finest. Even as someone who is more dedicated to fully original sources, this is probably our landmark in terms of bridging the gap between the modern quality the film should have and the video hell it has always been stuck in.

Thank you Harmy for continuing to better this massive undertaking.
