Sanjay,
Memories of image quality are notoriously unreliable, but you can at least test whether the difference between a 4.2 and a 5mm exit pupil has any effect on your perception of image brightness or color saturation without needing to find a 10x42 SV for comparison. Just make a pair 42mm stopdown masks to place on the front of your 50mm binoculars. Any thin stiff opaque material will do, like black pasteboard. Cut to the right size and tape to the objective trim rings and you have a binocular that should behave very much like a current 10x42 SV. I would start by placing a single mask on one side and leave the other side unmasked. Look back and forth between the two sides with one eye.

Hmm that's sound some real interesting experiment. Let me see if I can simulate. What is your opinion on color saturation with higher exit pupil. Does this makes difference. I did try bino during the day time when there was adequate light and hence the time when it should play the least. I am not sure if El have different transmission curve over visible spectrum to give different charachteristics to different size ELs.
During the day when I looked down from building it gives me different level of clarity vs when I look straight through my binocular. I am not sure if stray light plays role when looking straight vs looking down. View looking down is crystal clear vs when you look straight and little far. There seems to be some haze which makes it less crispy.
