Without knowing what flavor profile you're seeking from your yeast: Most likely, yes, pitching at that high temp (beyond the recommended range from WL) will lead to some off flavors. Those off flavors may, or may not be, significant while drinking the final product - you'll just have to wait and see what comes.
Remember, the key practices that lead to successful brewing are:
- Temp control
- Yeast Health
- Ingredient Quality Control (including water)
