Devil's Canyon is a refresh of Haswell....see below.
Devil's Canyon applies to the "k" versions from what I'm seeing.
If the CPU is showing up as a "k" version, I wouldn't be concerned about what CPU-Z is reporting for a code name.
Haswell Refresh[edit]
Around the middle of 2014, Intel released a refresh of Haswell, simply titled
Haswell Refresh. When compared to the original Haswell CPUs lineup, Haswell Refresh CPUs offer a modest increase in clock frequencies, usually of 100 MHz.
[74] Haswell Refresh CPUs are supported by Intel's
9 Series chipsets (Z97 and H97, codenamed
Wildcat Point), while motherboards with
8 Series chipsets (codenamed
Lynx Point) usually require a BIOS update to support Haswell Refresh CPUs.

The CPUs codenamed
Devil's Canyon, covering the i5 and i7 K-series
SKUs, employ a new and improved
thermal interface material (TIM) called next-generation polymer thermal interface material (
NGPTIM). This improved TIM reduces the CPU's operating temperatures and improves the overclocking potential, as something that had been problematic since the introduction of Ivy Bridge.
[76] Other changes for the Devil's Canyon CPUs include a TDP increase to 88 W, additional decoupling capacitors to help smooth out the outputs from the fully integrated voltage regulator (FIVR), and support for the
VT-d that was previously limited to non-K-series SKUs.
[77] TSX was another feature brought over from the non-K-series SKUs, until August 2014 when a microcode update disabled TSX due to a bug that was discovered in its implementation.
