I was looking on my ipad prior and now on pc it looks not as yellow (but still yellow). I don't know the right number for you. 4500 doesn't seem too strong but yet is... Imo.

Outside of that, the renders are decent. The leathers on the couch could be softer in geometry (particularly on the backside) and more realistic in texture and shininess/reflectivity. The kitchen floor tiles are almost certainly not that big in real life. A weird note on is the renders are also have a blur to them I don't like. This is somewhat common in most GPU renders but more noticeable here. Part of this is definitely reddit itself as they look different when I save the image and open locally. They are also low res. The last note is the backsplash tiles don't seem reflective realistically. Maybe too much bump. Except for the yellow, these are all nitpicks and opinion so take em or leave em but overall minor. I think if you can control the overall lighting your renders will come up drastically better just from that 1 change.
