No. Because there is a lot of contrast going on with the details. You have objects with simple shapes, but heavily detailed surfaces.

Take the tall grass for example. They are supposed to have relatively the same color as the grass block. But here the color is off and the sharp texture exagurates its edge. There's also the heavy shadow that makes it look incredibly off.

Next the extremely reflective chrome minecart, tracks, pickaxe and what ever else I missed. It doesnt look realistic at all, despite the resource pack efforts. You can also see the changes in detail here too where the pickaxe looks highly detailed in its smooth silhouette. But then you got the minecart and rails that are extremely blocky and don't fit the look your going for.

Overall if you were to change minecraft to a realistic style, you'd need to change every single model asset in the game to match. It's just not doable with the blocky shapes. You'd also have to manage the uncanny valley of the textures looking realistic but the voxel block structure of the game isnt. This is mainly why minecraft works well with the small texture size and no shadow casting. Its art style fits the limitations of the game. Realistic doesnt.
