Sabino cannot and does not cause blue eyes. By that very fact, it is impossible that this horse is JUST tobiano/sabino. A chin spot can also be indicative of splashed white.
I'm not seeing frame, that's a gene that wants to inhibit white on the legs if it can, and will try to disallow a chin spot. It also causes white markings to spread out above the eyes. I'm not seeing any of that happening in this horse.
It's hard to say for sure what this horse carries other than tobi and sabino (because sabino avoids the eyes and splash/overo does not, and this face marking clearly avoids the eyes, there is no doubt that sabino is there). It may be frame, but I'm not seeing it. It may be splashed white, but I'm also not really seeing that. It would help if you could get some more photos of the face marking, from the front and from both sides.
All I am saying is that there IS something else, this horse is not just tobiano and sabino.
