Isn't it taller, but less wide, and thinner? There total surface area is probably bigger (height increased about 1cm whereas width decreased about 3mm), but I think it will feel smaller in your hand. When holding a phone, it's generally the width & thickness that makes it feel big. Both of those dimensions decreased.

If you're talking about thumb-stretching to reach the top of the screen, though, that might get a bit more difficult.
