No data, but as a user I do expect to see a card type selector or indicator, even though I rationally know its superfluous.

Unfortunately I don't have actual numbers for you, but a company I used to work for that did a fair bit of CPO had good data that removing that selector reduced conversions (the most interesting thing to come out of that study was that, at the time and with our client base, removing the actual card logos (e.g. leaving only the textual names) increased conversions).
