I defer to OCIO experts on the details, but yeah, if you're just trying to get
it from sRGB into ACES, then I believe it's generally --colorconvert that you
want to use, not --ociodisplay.
So something like
oiiotool my.jpg --colorconvert srgb_texture acescg -o acescg.exr
Also, you can use --autocc to do it all automatically upon input and output, if
your studio has a convention of embedding your color space namesake in your
filenames!
oiiotool --autocc my_srgb_texture.jpg -o my_acescg.exr
