You will find many reviews of the X-T5 but if you are interested in my 2 cents worth of an opinion then I love this camera. I think it is very good esp. for the things you shoot more. It can be rather small if you use the smaller lenses like the 27mm, 35f2, 50f2… great for landscapes, street and travel. Very customisable, wonderful controls where you can set up your main parameters by turning physical knobs - simple and fast. Very satisfying to use. I shoot manual all the time, using the histogram. Big choice of very good lenses, big and small, expensive and inexpensive. Weather proof, decent battery life. Fantastic image quality, Fuji colour magic. Some people claim that continuous tracking AF is not as stellar as Sony or Canon esp. for people zig-zaging with closed eyes in the shadow under a baseball cap but I couldn’t care less for that. For birds in flight you would probably be better off with a different camera but otherwise, for the things you do, very very good value for money and a real joy to use. Have a look at the user’s manual to see what it can do. You can also go and look into my photos in my Winter Landscapes topic but then you must give them all a like so reserve some time for that  😀. (Photos are resized by this site so you know... I can send you some full-sized RAWS if you want.) Cheers and let us know how you got on. 

The IQ (recipe) settings do not affect RAW files except for the Dynamic Range (DR) setting, which may force a higher ISO (DR200 requires base ISO x 2, DR400 requires base ISO x 4). Since a basic exposure parameter is affected, this does propagate to the RAW file. Please note that as mentioned above, Lightroom's Camera Profiles for the X-T5 do have film sims but (a) they're not necessary exactly the same as the built-in ones, and (b) they do not account for the other IQ settings such as tone and clarity. Those you will have to apply to the RAW file yourself in Lightroom. Capture One seems to have the closest approximations of the Fuji film sims, but again, you have to apply the other settings using the software sliders. If you're interested in keeping everything 100% Fuji, try the Fuji X RAW Studio software, which lets you play around with all of the IQ settings on your computer (but you do have to have your camera plugged in and USB set to BACKUP mode). This is the software a lot of people use to design new recipes.

If you didn't shoot in RAW and only have JPEGs to look at, it's quite possible the grain setting was on. This might be reflected in the EXIF data of the JPEG. Not sure if C1 would show it but if you load it up in Fuji X RAW Studio, you should be able to see it under GRAIN EFFECT.

Maybe this is better....
