Short description of error
Non float images have float buffers if displayed in the Image Editor once

Exact steps for others to reproduce the error

go to the shading workspace
add an image texture and load any 8bit image
bpy.images['myImage'].is_float should be False
select that image in the Image Editor
bpy.images['myImage'].is_float is now True

So the ImBuf now has a rect_float and this will not go away (also not when no Image Editor is shown)
This is misleading, checking this in python is now unreliable and this also has other consequences such as the Half Float Precision option always showing for such images.
