Is DJI Copying Fujifilm?

Someone pointed out something interesting to me: the new DJI Osmo Pocket 4 has “Film Tones” that take close inspiration from Fujifilm. Specifically, CC Film and NC Film are “Fuji-inspired” (as DJI puts it), and are obviously similar to Fujifilm’s Classic Chrome and Classic Negative Film Simulations (apparently, CC Film more so than NC Film). These are intended to give a finished look straight-out-of-camera. First, as Oscar Wilde famously stated (or maybe he didn’t, it’s apparently debatable), “Imitation is the sincerest form of flattery that mediocrity can pay to greatness.” That’s not a dig on DJI, but simply noting that 1) Fujifilm’s Film Simulation are both great and popular, and 2) someone’s approximation of it will never be quite the same as the real thing (but maybe it doesn’t need to be). If something is successful, there will be copycats—sometimes close copies and sometimes more of an “inspired by” situation. I’m not sure what type of copyrights and trademarks Fujifilm may…
