Assuming this is a desktop build, I wouldn't stress about Meltdown too much. It is mainly a concern for service providers which allow multiple users to run code on the same physical CPU.
Also note that as far as I've seen, no matter what variant, the number of exploits "in the wild" as the phrase goes, is still zero.
JihadJoe is likely right though in that the programs are unaware of the fact that CoffeeLake-R has mitigations in hardware, and have probably not been adapted to the newest silicon.
