Is it necessary to check filter_access() on GET requests?

In RestfulEntityBase, at line 946, we have the following code:

```php
// Check format access for text fields.
    if ($property_wrapper->type() == 'text_formatted' && $property_wrapper->value() && $property_wrapper->format->value()) {
      $format = (object) array('format' => $property_wrapper->format->value());
      if (!filter_access($format, $account)) {
        return FALSE;
      }
    }
```

Basically, if a user makes a request to the endpoint, it makes sure that the user has access to the particular input filter that the property returns.

However, if you are just GETing the response, and viewing, for example, a blog article, then we shouldn't need to check this, correct?

Right now I'm doing this:
```php
if ($property_wrapper->type() == 'text_formatted' &&
      $property_wrapper->value() &&
      $property_wrapper->format->value() &&
      $this->method != 'GET') {
      $format = (object) array('format' => $property_wrapper->format->value());
      if (!filter_access($format, $account)) {
        return FALSE;
      }
    }
```

My question is: is it necessary to check for filter access, if we're just viewing an entity?
