Do bump textures benefit from 16bit per channel?

Questions
1

Hi,

I’m currently working on generating normal maps, and while everything seems to work well, when i generate a 16bit per channel png, there is no additional detail visible when applying that to a PBR material against a downsampled 8bit png, even though the 16bit png clearly contains more details when analysed with image editing software.

Does Babylon.js downsample 16bit png to 8bit per channel? And if so is there any way around it?

Thanks in advance

it is not bjs but the browser which will force us to use 8 bits per channel unfortunately
