I used this texture in Rhino 7 and it displayed as expected.

Light Bloom 05
Light Bloom 051080×3456 1.55 MB

It looks like this in Rhino 7 (default wireframe display mode):

Light Bloom Texture in Rhino 7382×923 51.7 KB

But it displays like this in Rhino 8 (default wireframe display mode):

Twiddling with the material, texture and display settings has not helped so far.
Can anyone help me?

Here is a Rhino 7 file with the texture embedded.

Could this be a gamma correction thing?
Or a colour space thing?
