Plus, since mine was in a darker environment than yours, its no surprise mine has a lot more noise
Every light level has its proper exposure and if you did expose properly the noise will be the same. You can use ISO 3200 in bright light and expose f/16 and 1/8000 or in dim light expose f/1.4 and 1/10, if both exposures are the right ones for the ambient the same amount of light will reach the sensor, thus the noise will be the same. [Leaving aside the factors of long, more than a second, shutter speed or the effect of light temperature on noise.] OTOH, if you set ISO 3200 and underexposed and then pushed it in LR, that is no longer ISO 3200 and blaming the camera is inappropriate.
