The 'right' temperature is what makes a white object appear white. Of course in practice most 'white' objects are not perfectly white, so unless you snapped a grey card it's quite hard to get it just right, but if it looks right to you it's unlikely anyone else will notice.

Yes, it's stupid annoying when they don't read the description or know how to Google, but I feel it's okay to ask questions to confirm that's you're getting what you expect. "Is this compatible with this camera" isn't always a simple question to answer unless you're quite familiar with the ecosystem, and even if a person can figure out the answer, it doesn't hurt to confirm with the seller who may well know the equipment better than you.
Even a question like 'what mount does this use?" - you might have written EF in the description, but if they don't know that EF is a type of mount then reading the description isn't enough, and for stuff like lenses the model name is more of a description and it's easy to get them mixed up.
