There is a difference between Ilford Multigrade developer and Dektol. For starters, the Ilford developer is a PQ formulation, while Dektol is a MQ developer. I don't know if the substitution of Metol instead of phenidone makes much difference, but the restrainer used certainly does. Ilford uses benzotriazole which will retain the cold tones better than the potassium bromide that Kodak uses in Dektol. I think that a warmtone developer certainly will change the tone of the paper. Warm tone developers tend to be less strong versions of classic MQ formulations with a bit of extra bromide included. I start out with a more dilute version of Dektol, and the paper warms up as the bromide levels increase with use.
