Oh I am sure those are in there as well, but the way the color is over the rump is what is telling me frame. I see sabino as well with the "roaning" of the color over the rump.
As to what other white patterns are for sure there... only one my gut is telling me for sure is frame, with a very strong feeling of sabino. Splash is also probably there, but so hard to tell with there being so little color.
*disclaimer I am probably not making sense as I can't even think straight. My bed is calling my name.
