Same here. Region A Blu-rays I play on my default LG UHD/BD/DVD player. I also have a switchable-region LG Blu-ray player that I just leave set to RB (it's automatically multi-region for DVDs).
Since Disney owns its films outright worldwide, I believe they release everything (or most things) region-free. At least, I've never come across any non-US-release Disney disc that wasn't.
Are you sure about Ang Lee? If you're referring to Life of Pi, I never got around to seeing that in 3D, and based on the 2D version, I'm sure I would've loved it (I've also heard nothing but great things about the 3D version).
But his most recent 3D film was Gemini Man...
On edit: Of course...
