I was wrong, I just realized that arb_copy_image-formats was not part
of my test-set and it still fails because it allocates one texture as
four component and the other as three component. same for 

dEQP-
GLES31.functional.copy_image.non_compressed.viewclass_96_bits.rgb32ui_r
gb32f.texture2d_to_texture2d 

Interestingly dEQP-
GLES31.functional.copy_image.non_compressed.viewclass_96_bits.rgb32ui_r
gb32i.texture2d_to_texture2d passes

Best,
