My understanding is that Spectre will allow an attacker to read any memory anywhere in userspace, so yes, that would include the clipboard. Meltdown is just an enhancement to Spectre that allows it to also read into kernel space (ring 0). Spectre is the systemic issue that accurately deduces memory values based on CPU cache heat. Meltdown is the implementation-specific issue, which affects many ARM SKUs and virtually all Intel SKUs, that makes privileged memory susceptible to the same.
