No.  The trailing .0 is only there to appease programs that do not work
with a two-digit kernel version, which is also the reason why Linus
numbers his releases as x.y.0(-rcN) rather than just x.y(-rcN) .

You can learn more about the numbers used in Debian kernels and what
they mean in the Debian Kernel Handbook[1].

The upstream version of the Debian kernel is available with "uname -v":

| $ uname -v
| #1 SMP Debian 4.14.12-2 (2018-01-06)

Here 4.14.12 is the upstream version, and the -2 indicates the Debian
revision, not to be confused with the ABI version that appears in
"uname -r":

| $ uname -r
| 4.14.0-3-amd64
