he'd see the other two have the same dot color and would assume his would be different

The first answer works well - They are stated to be masters of logic - and all hands are raised so obviously anybody who can see a blue dot knows they have a red dot pretty quickly. Nobody does this so the next conclusion is nobody can see a blue dot.
But the second answer is much nicer - the grand master will design a fair test - clearly if the dots are different colours somebody has an advantage.
The nice thing about these solutions is that they don't conflict - but the time delay suggests that the first answer is the intended one.

Masters of Logic Puzzles I. (dots) - Back to the Logic Puzzles
Three masters of logic wanted to find out who was the wisest one. So they invited the grand master, who took them into a dark room and said: "I will paint each one of you a red or a blue dot on your forehead. When you walk out and you see at least one red point, raise your hands. The one who says what colour is the dot on his own forehead first, wins." Then he painted only red dots on every one. When they went out everybody had their hands up and after a while one of them said: "I have a red dot on my head."
How could he be so sure?Spoiler for Solution
AND NOW I HAVE A HEADACHE!!!
