ImHex will tell you if it's compressed. Do you understand data structures? Floats, all those data types? I'd suggest looking at a format like msgpack to see what a binary data format could look like: https://msgpack.org/ https://msgpack.org/ Then be aware that proprietary formats are going to be a lot more complicated. Or maybe it's just zipped up json data, only way to tell is to start poking around at it.
