I think it's OK.
1. You've overestimated the "reach" area a bit, IMO
2. you've placed the screen too high (further extending the "reach" area) vs. the leaked parts.
3. there's not a lot up there that you need to reach for. You've pointed out the back button, but those are pretty big -- easy to reach for.
All and all, yes, a few things will be harder for those with small hands to reach... but against the positives of a larger screen, I don't see this as 95% good, 5% bad. So, a very good thing.
